(这是一条买家关于"Sales Tax exemption form sent"的询盘信息,来自第108届中国广交会。)Inquiry Message (询盘信息) Sales Tax exemption form sent To whom it may concern: On 5/20/09, a Wisconsin certificate of previous purchases was mailed to your Dallas office for a purchase per your invoice # 870437 dated 12/17/08. Can someone look into the whereabouts of this form and let me know the status of the refund request(your action date). I would like to add to the form before anything further happens on your end. Can someone let me know the period of time that I can go back to? I know of at least 2 purchases in 2009 that were taxed but should not have been (e.g. t.p.p. used in an exempt manner). There are probably others in 2008 and prior year(s). Thanks for your help. Contact Info (联系信息) Joh" Grind flat 17-4 SS Grind flatness+/-.005 and paralles+/-.005 17-4 SS 31""x31""x.5""
